Tactics for the Swamp (Fortress).

when playing with random settings, the artifact that removes positive morale brings me the most joy.

I agree: the Spirit of Despair is a very valuable item (unlike the Sands of Time, it's actually useful)! It's especially needed if we're relying on Berserk: then we can be sure that the berserked enemy stack won't flinch and attack a second time – but this time against our troops!
